| DTaP vaccine protects against tetanus, diphtheria, and pertussis. |
People who got all their vaccinations against tetanus and diphtheria in childhood don’t need booster shots to remain protected against the two rare but dangerous diseases, researchers conclude in a new study that found no difference in disease rates between countries that recommend adult revaccination every 10 years and countries that say completing childhood vaccinations is enough.
As of 2017, the World Health Organization recommends vaccinating adults against tetanus and diphtheria only if they didn’t finish their childhood immunization series or don’t know whether they did. The guidelines make exceptions for pregnant women, some types of international travel, and tetanus-prone injuries. But in the U.S., the Advisory Committee on Immunization Practices, which makes recommendations to the Centers for Disease Control and Prevention, currently favors booster shots every 10 years for adults.
The CDC declined to comment on this new study, published Tuesday in Clinical Infectious Diseases.
In what the study’s senior author called an “embarrassingly simple” experiment of nature, researchers compared disease incidence over 15 years in 31 industrialized countries in North America and Europe with similar health care infrastructure and socioeconomic status. They analyzed data from the WHO, adding up to more than 11 billion person-years. The paper looked particularly closely at France, which recommends 10-year booster shots, and the United Kingdom, which has never done so.(READ MORE)
